Dr. Demento

Barret Eugene Hansen, known professionally as Dr. Demento, is an American radio broadcaster and record collector specializing in novelty songs, comedy, and strange or unusual recordings dating from the early days of phonograph records to the present. Hansen created the Demento persona in 1970 while working at Pasadena, California station KPPC-FM. He played "Transfusion" by Nervous Norvus on the radio, and DJ "The Obscene" Steven Clean said that Hansen had to be "demented" to play it, and the name stuck.
